40% of farmers are likely vote Yes to the the Lisbon Treaty while 33% say they are likely to vote No, according to a new poll.
However 27% farmers do not yet know which way they will vote on 12 June, according to the poll conducted by the Irish Farmers' Journal and RED C.
Out of the 619 farmers questioned, 78% described themselves as either 'quite concerned' or 'very concerned' about EU Trade Commissioner Peter Mandelson's handling of the WTO talks.
76% of those polled said they would take 'guidance' from the IFA when making their final decisions on the Lisbon Treaty.
The poll was conducted between last Tuesday and Saturday.
The usual age, gender and demographic principles were used in the poll.
People Before Profit Alliance has launch campaign
A group campaigning against the Lisbon Treaty has claimed that people are being kept ignorant about what is in the treaty.
The People Before Profit Alliance has launched its campaign calling on people to vote No in the upcoming referendum.
The group says it will be distributing thousands of leaflets and canvassing doors in 15 constituencies as part of its campaign.
The alliance describes itself as a group that wants to reverse policies that place wealth creation for the few over the welfare of communities.
It is opposing the Lisbon Treaty on three main grounds.
It says the treaty will lead to a further militarisation of the EU and obliges member states to make their facilities available for EU military activity.
It claims Lisbon reduces the areas where governments can veto policy proposals.
And the alliance also claims that the treaty makes privatisation of public services, including health and education systems, easier.
The group claims voters are not being given the facts and says voters should not be bullied into voting yes.
No campaign posters identified
In relation to a different No campaign, the Labour Party has claimed to have identified the source of apparently anonymous posters.
The posters, which have recently appeared on lamp-posts in part of Dublin, call for a No vote in the Lisbon Treaty.
It is illegal under the Electoral Acts to put up posters without identifying the publisher.
Dublin Central TD Joe Costello said that in the tiniest possible print, the publisher is identified as an organisation called 'Coir', which shares an address in Capel Street with organisations such as Youth Defence and the Pro-Life Alliance.
Deputy Costello claims the posters, including one with the message 'People Died For Your Freedom - Don't Throw it all Away, which features a reproduction of the 1916 proclamation, are misleading.
He claims the organisation appears to have 'vast sums of money' at its disposal, and challenged it to disclose the source of its funding.
